Zend Framework

Zend is an open source tool built on PHP5 for web application development. Withstanding competition from Ruby on Rails and Spring frameworks, the brilliant architecture of Zend ensured that it gained recognition among web developers. Within a few years of its release, Zend framework is now used by thousands of developers to create web applications. Perhaps the USP of Zend is its MVC (model view controller) architecture, which separates data and user interface, enabling developers to alter the database without affecting the user interface.
